<h3>QTopo - Points</h3>
<p>
<br>
<p>

To add points to the plot you switch to <i>Point insert</i> mode
and click where you want to put the points.
In this mode the cursor is a cross-air, and the <i>Mode</i> button
shows a cross.
<P> 

Only a few Therion point types are supported and there is only a limited
support for their options.
<ul>
<li><i>station</i>. This is somewhat special. You insert a station point
by clicking on its name in <i>Select</i> mode. If you click again on 
the name of a station point you have already added, a point-comment dialog
shows up where you can enter a description for the station.</li>
<li><i>air-draught</i>. Displayed as a light-blue arrow.
It has an orientation.</li>
<li><i>blocks</i>. Displayed as a gray square.</li>
<li><i>continuation</i>. Displayed as a question mark '?'.
When you add a continuation point a dialog box opens up for the
optional text of the point. Type it in and press the "Enter" key.</li>
<li><i>debris</i>. Displayed as a pair of gray triangles.</li>
<li><i>sand</i>. Displayed as a pair of gray rectangles.</li>

It has an orientation.</li>
<li><i>clay</i>. Displayed as a gray curly shape.</li>
